https://reviews.llvm.org/D43791 wasn't quite enough because we often run out of inlining stack depth limit and for that reason fail to see the atomics we're looking for.

Add a more straightforward false positive suppression that is based on the name of the class. I.e. if we're releasing a pointer in a destructor of a "something shared/intrusive/reference/counting something ptr/pointer something", then any use-after-free or double-free that occurs later would likely be a false positive.
